Had another one that struck me as odd. I didn't take notes at the time, so these are paraphrases.

First: "[Player] is injured and has to be stretchered off! It didn't seem that serious at first"
Me: Oh crap. OK, put in a sub for him...
Then: "[Substitute] comes in. [Injured Player] goes off and is not too happy about it!"

The only other time I've seen that second status is when I pull someone who's having a good game. Dude, you don't get to complain about being subbed out if you can't stand up. You are not Monty Python's Black Knight.
